TiNx and TiOx/TiNx Barrier Layers for Al‐Based Metallization of Passivating Contacts in Si Solar Cells

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.
A Ti‐based diffusion barrier layer is presented for Ag‐free contacting of passivating contacts for crystalline Si‐based solar cells, enabling the use of standard screen‐printed Al‐paste. This approach provides an alternative to Ag‐based contact electrodes, while still maintaining high surface passivation quality and enabling low contact resistivity ...

Gallium β‐Cyclodextrin Nanoparticles Containing both Gallium Protoporphyrin and Gallium Nitrate Exhibit Antimicrobial Activity against Nontuberculous Mycobacteria in Vitro and in Vivo

open access: yesAdvanced Therapeutics, Volume 8, Issue 11, November 2025.
Cyclodextrin nanoparticle containing both Ga(NO3)3 and GaPP is synthesized and tested against non‐tuberculous mycobacteria (NTM). The in vivo efficacy of the nanoparticle therapy is additionally tested by treating pulmonary NTM infections in mice and observed much greater effectiveness in bacterial clearance and survival of mice.

Board busyness and financial leverage: The impact of corporate tax avoidance

open access: yesFinancial Review, Volume 60, Issue 3, Page 951-1002, August 2025.
Abstract This study investigates the impact of “busy” independent directors on corporate financial leverage. Using a sample of 3321 Chinese listed firms from 2004 to 2019, we find that firms with busier boards tend to have higher leverage, with corporate tax avoidance acting as a mediating mechanism.
